| 説明 | This is a scatter plot of vehicle schedule deviation plotted against time of day. Time of day is plotted on the horizontal axis with gray tick marks every hour. The slightly bolder gray line is noon. Schedule deviation is plotted on the Y axis, with three ticks, from top to bottom: five minutes late, on time, and five minutes early. There's a dense area right after noon - this doesn't represent any feature of King County Metro's schedules - it's just a region where I got two day's worth of readings. On average vehicles are about a minute late. They're rarely more than two minutes early, but it's not terribly uncommon for a vehicle to be up to twenty minutes late. |
